Problem 19.11
Carla is a statistician with a bank. She has collected debt-to-equity mix data on mature (M) and young (Y) companies. The debt percentages vary from 20% to 80%. Carla has defined DM as a variable for the mature companies from 0 to 1, with DM = 0 interpreted as the low of 20% debt and DM = 1.0 as the high of 80% debt. The variable for young corporation debt percentages DY is similarly defined. The probability distributions used to describe DM and DY are
